To all whom it may concern Be it known that I. Pmur ARBOGAST, oiPittehurg. in the county of Allegheny and Stnteof Pennsylvania, haveinvented certain new and useful improvements in the Manufac .turoofGlassware and I dohereby declare that the following is nfulhcleer, andexact description of the invention, which will enable others skilled inthe art to which it upper-rains to make andnse theeame, reference beinglied to theaccompanying drawings, which form a part and in which- Figure1 is a vertical section of'my preparrug-press; Fig. 2 is n similar viewof the mold with a. bottle in the act of finishing. Fi shows a formgiven bye, modification of the preparing-press. Fig. 4.- shows insection nrest for extra. glass. Fig. 5 is a' modification of Fig. 1.Figs. 6,1,nnrl 8 show different articles mafde by my invention.

This invention relates to the manufacture of glassware as are desired tobe produced with a pressed or molded portion, generally the month, whilethe remainder is blown in'a mold. Such articles are bottles, frnitiars,lamp-chimnc5s,lnnter|1-glohes,lenrp- In the manufacture of thisclass of articles the body is first blown in a mold after l inving beenroughly shaped in the merrier. Then the article is clamped on o, tooland softened at the month, after which it is given the desired finishwith either a hand tool or press, in which operation some forms requirethe od dition of a. ring of extra glass to be stnck'oln'. All theseoperations are laborious and costly and require skilled labor.

My invention consists broadly the finished portion in a. suitablegather, or lump of molten glass, and at the some time pressing a cavityin the lump or form to serve as a basis for the subsequent blowing, thenremoving the lump from the press-mold, placing it in a separate mold andblowing till the in pressing lump has expanded to the form of the mold;

also, in the apparatus hereinafter fully de scribed and claimed.

As quickly no possible, and whilethe messis stillhot and soft, the mold A, is opened and the mass lifted ont,wit-h thering B still on it, (the ring having is suitable bundle or handles forthe pnrpose,) end lowered into a bottle-mold.

In small articles-such no prescription-bot: ties the process can, bereadily carried out by giving the prcpnretory mold A,-ringr B, andplunger the one shown in Fig. 5. Forench articles as hnve n sinnll neckor mouth and a very large body I would form the neck, as in Fig. 3, withas thin small body under it, and then insert it into a. larger andhotter m'ass,F, Fig. 4, and proceed as before described.

The object of the extension of the plunger into the dependent mass ofglass is not only to force the glass into all pnrte of the ring andpreparatory mold, but also to form n windcnvity l! the mass, which willmaterially help the blowing in the finishing-mold. I

In l ig. 6 l ehowncrimped and headed chimney, the crimperl top and bendbeing pressed (like the bottleneck) and the body blown in a mold, asbefore described. in thiscnse, and in all articles honing an openbottom, there will be e. blow-over, which must be broken on and ground.

be found advisable to blowing finally, which will be done without removing the ring; or the ring may be removed too.

The particular formof apparatus may be changed or modified without'departing from 1 therefore do not confine 'myselt'to the exact forms.shown.

It; is essential to the successful practice of the aboveinvention that;the plunger should be very quickly removed from the press-mold,

20f as otherwise either theplnnger will get heated and adhere to'theglass, or, it cool, will chill' the glass and preclude the possibilityof subsequent blowing. It is equally essential that two separate anddistinct molds be used, one

cause the moment the gather is pressed not be removed from its mold,

as,if it be allowed to remain there,

0 surface becomes ehiiled from eonlactwith the ent mass of glass,

"mold, and finally must be removed, but the mold and cannot be therbyblowing; so that; unless the gather is thus removed from contact withboth plunger and press-mold and placed in a separate niold for blowing,it is finished ware.

I am aware that it; has been proposed to press the article in a moldwhich finishes one part of the same, and then, while the article isstill in the same mold,'to blow the remainder of the article,;-: part ofthe mold being enlarger] for such .blowing, and the air passing throughthe plunger into the body of the an ticle. I do not, claim such process;but

What I claim as my invention is- The described improvement, intheinanul'aeture of glassware, consisting'inpressing the mouth or neck tofinished form with a dependthen withdrawing the plunthe article fromthopressinserting it 'in a, separate to form the body, substatiger, thenremoving mold and blowing tially as described.
